The Living Architecture Performance Tool (LAPT) is a program designed to set performance criteria and metrics for living architecture (green roofs, green walls, etc.) and foster best practices for the industry. The LAPT will be a voluntary standard, serving a diverse audience, including policy makers, water and energy utilities, designers, property owners, manufacturers, and researchers.

The development of the tool has been driven by workshops, consultations, and white papers developed by volunteers. The first version of the LAPT is now available in draft form for public comment. Please submit any comments by October 15th, 2017, to Rohan Lilauwala at rlilauwala@greenroofs.org.
